ANATOMY REVIEW
Due Tuesday February 1
Name: ______________________________________
INSTRUCTIONS: Please use a Scantron form 882-E or form 882-E-LOVAS to record your answers. This is a 100question GREEN Scantron – the brown ones won't work. You do not need to turn in this question packet, just turn in the
Scantron. This counts as a homework assignment and is an open-book review of anatomy. I expect the class average to
be 54 to 60 questions answered correctly, as you have plenty of time and can use your books and notes. You may work in
groups but be sure you understand the questions and answers. Feel free to send me WebCT mail if you have questions.
Choose the one best answer for each question.
